Hi! I have SBS 2000 installed on my server. So, ISA and Exchange are on the same machine. I have enabled SMTP filter, and configured it to reject messeges with .exe, .bat and .pif extensions. But it's not working. All mail with that kind of attachments are comig through? Any idea what is the problem? ------------------------------------------------ SIlVIU BONDALICI IT MANAGER DC COMMUNICATION, 6 Covaci St, Bucharest tel: (+4) 01 312.38.35/36 fax: (+4) 01 313.80.35 http://www.dccom.ro/ http://www.dccommunication.ro ------------------------------------------------
